This may or may not be the answer you're looking. I was classically trained to read music on the printed page and follow the musical road signs so naturally, I tried to do that with BiaB when I first started. That was an adventure in frustration especially the more complicated the musical directions needed to be.

My solution was to simply UNFOLD the song to a single chorus that was linear in it's path. No repeats... simply start at the beginning and go straight through to the end. Yeah, it uses more measures but I have never ever come close to running into the hard limit on the number of measures. Even the longer length songs rarely exceed 50% of the limit.... (Limit is 255 measures IIRC)

Build the song the way you want.... intro, verses, copy and paste for more, choruses, bridges, and the ending.... all in a straight linear line.

I love working in that linear form now.

You can make excuses or you can make progress but not both.

The magic you are looking for is in the work you are avoiding.
